So I have an event enabled PIO with a couple of Boolean parameters.   Up until now I've been using the below to get the parameter's current state by converting the string to bool, as GetRField returns strings, which I thought was fine. show_weight_bool = strtobool(vs.GetRField(objectHand, objectName, "Show Weight")) HOWEVER An unexpected bug has come up, from someone who tried this plug in on a non english version of Vectorworks (it was German in this particular instance).
